A more standalone version of my_tz_find(): will open tz tables if needed.
This is so far only used by replication, where time zone setting does not
happen in the usual query context.
SYNOPSIS
my_tz_find_with_opening_tz_tables()
thd - pointer to thread's THD structure
name - time zone specification
DESCRIPTION
This function tries to find a time zone which matches the named passed in
argument. If it fails, it will open time zone tables and re-try the
search.
This function is needed for the slave SQL thread, which does not do the
addition of time zone tables which is usually done during query parsing
(as time zone setting by slave does not happen in mysql_parse() but
before). So it needs to open tz tables by itself if needed.
See notes of my_tz_find() as they also apply here.
RETURN VALUE
Pointer to corresponding Time_zone object. 0 - in case of bad time zone
specification or other error.
